Chandan Purushothama created CLOUDSTACK-361:
-----------------------------------------------
Summary: Wrong creation of guest networks on a KVM host in
Multiple Physical Networks with guest traffic
Key: CLOUDSTACK-361
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-361
Project: CloudStack
Issue Type: Bug
Components: Management Server
Affects Versions: pre-4.0.0
Reporter: Chandan Purushothama
Fix For: pre-4.0.0
================
Steps to Reproduce:
================
1. Deploy an Advanced Zone Setup with Two Physical Networks and Ubuntu 12.04
KVM Host.
2. Physical Network 1 carries management, storage, guest and public Traffic
while Physical Network 2 carries guest traffic only.
3. On Physical Network 1, provide the KVM Labels for all the traffic types such
that they refer to the asfbr0 (bridge on KVM Host) while on Physical Network 2,
provide the KVM Labels for the guest traffic type such that they refer to the
asfbr1 (bridge on KVM Host)
4. Create the corresponding bridges on the Ubuntu 12.04 KVM Host which has two
physical nics.
bridge name bridge id STP enabled interfaces
asfbr0 8000.bc305bd41c36 no eth0
asfbr1 8000.bc305bd41c37 no eth1
5. Add the host to the Setup.
6. Create tags to the guest traffics of the physical networks
7. Create Two Network Offerings with the corresponding tags given for the guest
traffics.
8. Create two networks using the two network offerings and deploy a VM on it.
9. Observe the KVM host bridges information and notice the wrong creation of
the guest networks.
============
Observations:
============
**Note that the Management Server mentioned that the VLAN be created on asfbr1
bridge to which eth1 is plugged into**
